First with reference to Figure 35, along with oil pump 750 operates, oil is pumped into pump via path 100 in the direction of the arrow, and is discharged in path 106.Filter 26 is connected to crankcase by mounting bracket 950, and mounting bracket 950 has to be aimed at path 106 and to extend to the path 952 in filter 26.Referring now to Figure 36, oil pumped out filter 26, enter into the path 120 of crankcase portion 18 via the path 956 of support 950.As previously mentioned, path 120 and same diameter parts 268(Figure 10 and 14) corresponding groove 122 is crossing, to lubricate at bent axle part 268(Figure 37) on main bearing 70.As shown in figure 37, aperture 322 is also through bent axle part 268(Figure 37) extend with crossing with path 320, and make from path 120,122(Figure 36) oil can inlet passage 320.

As illustrated best in Figure 37 to Figure 39, the oil in path 320 is from path 322(Figure 38) be in both direction and flow.The oil flowed left observed in Figure 39 lubricates the joint between axle 820 and driving end 274.Bearing 912(Figure 39) also lubricated by path 324.As shown in figure 38, the oil flowed to the right then continues flowing via path 330 and enters into the internal capacity 342 of pin 264 via path 340.Oil is via path 350(Figure 15 of pin 264 afterwards) lubricating bearings 310.Excessive oil from bearing 310 drops back in the oil sump of crankcase simply.

Get back to Figure 36, via the oil of path 120 not only to the groove 122 delivered to around main bearing, and advance vertically via path 126, with to delivering to indentation groove 128(Fig. 8).A part for visible indentation groove in Figure 36.Referring now to Figure 41, via the oil of indentation groove 128 to path 470 and the passage 472 of delivering to cylinder sleeve 6.As previously mentioned, via the oil of path 470 to the path 520 delivering to cylinder cover component 8, but via the oil of path 472 to delivering to sparger 480, via nozzle 482 to delivering on chain.Return Figure 20 B, path 520 upwards extends, and is opened on the upper surface 502 in wall 560.As previously mentioned, oil is to the passage 630 delivering to cam retainer 600 afterwards, and afterwards, oil via each passage around camshaft to delivering on cam.

Referring now to Figure 42, from the water of water pump 24 via the pipe fitting (not shown) suction being attached to pipeline 850, and discharge via the aperture 842 of water pump cover 36.Water is via aperture 150 and flow out in crankcase portion 18 via passage 152 vertically afterwards.Referring again to Figure 40, water advances via the aperture 460 of cylinder sleeve 6 and surrounding cavity 462 circulates, with cooling cylinder wall 444 afterwards.As shown in Figure 41 and 43, water is to delivering to path 504 afterwards, enters into cylinder cap 8.As illustrated best in Figure 44, cooling water continues to circulate around path 510, and proceeds to water out via thermostat 980.

Referring now to Figure 45 to Figure 50, trunnion shaft 1000 is depicted as and comprises driving gear 1002, counterweight member 1004 and axle 1006.End 1008 comprises the driving end 1010 in tongue form.Gear 1002 comprises outer gear 1014 and recoil gear 1012.Multiple spring is located in gear 1012,1014 between two parties, with the torsion spring load between the coupling gear being provided in gear 1002 and gear 1002.Referring now to Figure 48 and Figure 50, gear 1014 comprises spring-reception recess 1018, and gear 1012 comprise corresponding there is inclined-plane 1022(Figure 50) recess 1020.Therefore spring will coordinate between recess 1018 and inclined-plane 1022, make gear 1014,1012 can flush ground seat each other and will put, and be subject to spring load and rotate.

Referring now to Fig. 1, will describe waste gas recovery room 1050, wherein waste gas recovery room 1050 makes crankcase blow-by be recycled back into suction port via valve 1050.As shown in Figure 51 and Figure 52, ventilation plant 1050 comprises opening to the opening 1054 in crankcase, and guide plate 1056 and 1058.Recovery room 1050 is connected to crankcase by discharge passage 1060.As shown in the arrow in Figure 52, multi-direction change is carried out in the gas leakage from crankcase, and this makes oil be separated with gas leakage, to make oil flow back to via discharge passage 1060, and gas leakage upwards can be extended via the valve 1052 be arranged on upper surface 1062.Leak gas afterwards via valve 1052, via closure and return and be reintroduced back to via suction port (546, see Figure 20 B).

Last with reference to Figure 53, draw filter 1100 and to be set to be positioned in engine sump and to be connected to suction pipe 86, so that oil is filled into oil pump.
